Hi friends,
I am making use of AVR Evaluation board v3 and ATMega16A as IC, HEXA FILE has created, but while uploading the hex file it is showing me unknown device.
I tried on command prompt and given the command as

avrdude -p atmega16 -P com6 -c avr910 -v -U flash:w:led.hex

and it is showing in command prompt as follows

Found programmer: Id = ""; type = ª

Programmer supports the following devices:
    Device code: 0xffffffff = (unknown)
    Device code: 0xffffffff = (unknown)
    Device code: 0xffffffff = (unknown)
    Device code: 0xffffffff = (unknown)
    Device code: 0xffffffff = (unknown)



Can anybody solve this for me

and 1 more doubt is I am making use of atmega16a and I have selected the ic as atmega 16,whether it results in the uploading problem
